Key Stuck in Ignition / Car Stuck in Park
I wanted to run this by everyone here to see what your thoughts were. I won't be by the car for a few hours but I figured I'd get some initial ideas before I started to look at this. When I attempted to leave for work this morning, I put the key in the ignition, turned it, saw the gauges start to sweep, turned to on and nothing. I tried to turn the key back to off to remove it but it was stuck. I could only get back to the accessory position but I had no power anywhere at this time. No dome lights, gauges dead, couldn't open the trunk, etc. I went back in my house for a few minutes and came back out to the garage and as I was walking up to the car all of the power was restored. I moved the key back to off and was able to remove it. I put it back in and was able to the start the car. I tested this a few times and all seemed OK until I went to leave and I couldn't move out of park. The shifter was just stuck. I tried this a few times as well but no luck. I eventually ran out of time so I just left in my wife's car and have been doing some reading online about possible cause - blown fuse, shift lock solenoid, etc.
This is a GT and I'll also note that I have the triple gauge stack with Speedhut gauges that I installed in the Spring of 2017 that have given me some problems off and on where they will randomly freak out and throw and assortment of errors - check engine, ABS fault, traction control, etc. that usually requires that I unplug the OBD2 plug and disconnect/reconnect the battery to clear. They are still installed and get power but I've had the OBD2 plug disconnected for a little while now just to see if I see those errors again so they're not actually displaying any data.
Anyone have any thoughts on what I should be checking when I get home? Thanks in advance.
